Abstract

A process for substantially removing and recovering unreacted diene monomer from ethylene propylene diene monomer resin produced in a fluidized bed reactor by purging the resin with steam in a purging zone, the resin being introduced in the purging zone at a temperature above the temperature of the steam in the purging zone. <IMAGE>
